I'm going to the tech talk in a few weeks, but I'm still not sure what I need to bring. I know there have been a few already, so I'm wondering what's necessary to bring. Am I good with my iPhone and iPad, or do I need to bring a MacBook of some sort? I'd appreciate any info. I don't want to show up with a full coding setup when it's not necessary, but I also don't want to go unprepared.
